Distance: About 3 miles for both the Creek trail and the Suicide Rock trail into The Reservoir.
Time: If you're just taking your dog to splash with canine counterparts and heading back, about an hour, add an extra half hour to if you're planning to visit the highly-vandalized, but locally renowned Suicide Rock and The Reservoir, which are just past I-215.
Trail: Instead of an incredible workout, this one's more of a light-afternoon hike to enjoy with your dog or to meet some dogs and then catch frat pledges painting "Sigma Chi Rules!" on Parley's most famous rock.
It's not for the uppity, and it's a bit noisy due to the nearby freeway. And The Reservoir, unfortunately, is a bit trashed. But its clean on the west side of the freeway, and most dog owners clean up after their pets.
Its proximity to the city also makes it a good lunch-break hike, and you've got to see Suicide Rock.
As you walk from the trailhead into the canyon, you'll notice a splits in the trail. Stay left, and it will lead to a shared bike/hike trail, which has historical markers along the way, including Joseph Pudler's wine cellar, which dates back to 1870. Stay right, and you'll walk by the creek and over a cool wooden bridge. There are other options, but if you keep heading east, they'll all reach still water for dog play in the shadow of the Sons of Utah Pioneers building on the cliff above.
Once you reach the area where dogs congregate to splash, look left for the shared bike/hike trail, which will lead to a bridge crossing I-215. Go over the bridge, make a right and go down the hill, which will lead to the dirt trail leading to Suicide Rock.
Who you'll see: Bikers, families and many, many dogs. Maybe some taggers if you cross the bridge at the right time of day.
The Story: Legend goes Suicide Rock was a watchtower for local Indians. After a young maiden's brave died, she jumped from the top of the rock to join him in the afterlife. Now, it's a billboard for youth with spray cans. Wildflowers sprout among the tags—which are not exclusive to the rock.
How to get there: Park at or across the street from Tanner Park, 2760 S. 2700 East (right by Kol Ami Synagogue). Walk up the hill for a minute, turn left and you'll be at the trailhead.
